Application

  • Waste water re-pumping at the points where direct connection to sewerage is impossible because of the difference in height
  • Captation of rain waters with consequent use for irrigation

Design

  • Pump sump is of cylindrical shape, welded of polypropylene boards or centrings resistant to lyes and acids
  • The structure guarantees water tightness and resistance to underground waters as well
  • The sump is fitted with a mouthpiece to connect inlet pipe and with a flange for delivery pipe

Operation and Maintenance

  • Operation of the pump located in the sump is automated by the float level switches
  • Requirements for the regular maintenance are limited to the visual inspection of float switches and pump

Structural Advantages

  • Additional heat cladding for the winter operation is not required
  • The self-supporting structure does not require basic constructional preparation
  • Easy and quick installation on the base concrete slab
  • Safety is guaranteed by the walking metallic lid with anti-skid surface treatment fitted with a lock
